Ubuntu 20.04 LTS is a supported release; so why would it be found in old-releases as per your post?
Only unsupported or EOL releases are found there and whomever moved it there is many years too early.
Ubuntu 20.04 LTS has standard support until 2025-April, and ESM support for a further 5 years before it reaches EOL and gets moved to old-releases.ubuntu.com (which will occur sometime after 2030-April)
Someone with sudo rights has changed it incorrectly on your machine; reverse that change (ie. those lines should be and not )
